IMPROVEMENT IN SE PARABLE BUTTONS. I

Specification forming part of Letters Patent No. 216.97 I, dated July 1,1879; application filed May 13, 1879.

To all whom. it may concern:

Be it known that I, GEORGE PITTs, of Providence, in the State of 'RhodeIsland, have invented an. Improvement in Separable Buttons, of which thefollowing is a specification.

The nature of my invention consists in constructing a separable buttonwith a solid flat post attached to the under side of the upper portionof the button, and grooved at its edges in order to receive and securelyhold the spring employed for locking the two parts of the buttontogether.

Figure l is a back view of the upper portion of the button. Fig. 2 is afront view of the back portion of the button. Fig. 3 is a longitudinalsection taken in line av 00. Fig. 4 is a cross-section taken in line y 3Fig. 5 is an enlarged view of several parts of the button.

In the drawings, A represents the lower portion of the button, providedwith the tubular hollow post 13, having at its upper end the interiorcatch-flanges O .0, arranged to catch into the notches or bends D D ofthe spring E, which is operated to release the upper portri of i of thebutton by means of the pushers The groove G is struck in the raisedcentral portion of the plate H, in order to receive the inner ends ofthe pushers and operate as a guide for the same.

The post I is made from a flat piece of stock, grooved upon the threeedges J J J, and the spring E is firmly secured within these grooves bysimply bending down the side flanges, j j, upon the top of the spring. I

In putting the several parts of my improved I button together, I firstsolder the post I lengthwise over the groove G in the plate H, so as toleave a passage underneath. I then pass the pushers F F into the'outerholes, 70 7c, in the rim K, and into the central groove, G, under thepost, and place the bent spring E into the grooves in the edge of thepost I, so that the ends of the spring may loosely enter the notchesffin the pushers F F. The side flanges, jj, are then bent down over themiddle of the spring, by which means it will be securely held in place.

The above operation is so easily and rapidly performed and the parts areso simple and readily made that the whole constitutes a very desirableimprovement in the manufacture of separable buttons.

I claim as my invention-- 1. In a separable button, the plate H,provided with the groove G, and the flat post I, provided with groovesin its edges, in combination with the spring E and pushers F F.

2. In a separable button, the bent spring E, secured to the flat solidpost I by turning down the longitudinal flanges jj upon the top of thespring.

3. In a separable button, the pushers F F, provided with the notches ff, for the loose reception of the ends of the spring E, securedlongitudinally to the edge of the flat solid post I.
